aMultidrug-resistant (resistance to four or more classes of antimicrobials), coagulase-negative Staphylococcus.
†:MDR, multidrug-resistant, resistance to at least isoniazid and rifampicin; ‡: cOR, crude odds ratio; *aOR, adjusted odds ratio, adjusted for sex, age, treatment history, area and cigarette smoking; #:Those having previously received anti-tuberculosis treatment for more than one month was defined as previously treated cases; &: 8 cases with missing value.
As the team ruled out possible explanations, frustration gave way to the elated suspicion that the improbable was true: the drug they had discovered was resistant to resistance itself.
So far, the team reported that R2R-1 appears to be resistant to resistance, safe and highly potent.
Objectives: A method with improved capability for identifying an isolate as acyclovir (ACV) or penciclovir (PCV) resistant when resistance is borderline could greatly improve the management of HSV disease.
However, the reason that some tumor cells are inherently resistant (intrinsic resistance) without previous drug treatment is not known yet.
Only piperacillin-tazobactam showed reliable activity against P. aeruginosa (9% resistant), while resistance to all other agents was >19%.
For purposes of this study, the terms "resistant" or "resistance" refer to strains with zone diameters below or MICs above the susceptible breakpoint.
All strains were multidrug resistant with resistance to trimethoprim-sulfamethoxazole (SXT), nalidixic acid (NA), and streptomycin (S); all carried the SXT genetic element.
